Chemical Structure

3-(Diphenylphosphino)aniline CAS 36267-33-1 chemical structure

Description

The occurrence of 3-(Diphenylphosphino)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(Diphenylphosphino)aniline (CAS 36267-33-1) is a high-purity analytical reference standard with the molecular formula C18H16NP and a molecular weight of 277.30 g/mol.

Structurally, 3-(Diphenylphosphino)aniline (C18H16NP) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 277.30 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-(Diphenylphosphino)aniline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
